Upgraded the OS version to 10.6.6. Upgraded the EyeTV version to 3.5. Upgraded the Antenna to better quality. Lost Signal Quality on HDHomerun the last few weeks. Any suggestions to troubleshoot? I tried Coax change, Cat 6, direct connection to new and old antenna. Left trouble ticket with EyeTV. Lost signal within the last month. HDHomeRun made in 2009. I don't think it would have gone bad already. I also use the EyeTV 250plus also. Went from 3 tuners to 1. Appreciate any suggestions. Monday night: No response from the HDHomerun tuners at all. Buying new HDhomerun from NewEgg. Concerned that the lifecycle is 2 years for the tuners. New HDHomerun works properly. Just did not know the old unit was going bad.
